Planning Application Services | DOR Architects

Introduction

Every London borough has its quirks. If you’ve ever tried to secure planning permission in Camden, you’ll know it can feel like presenting a design dissertation – heritage officers scrutinising every line, neighbours quick to object, and conservation policies ready to trip you up. Contrast that with Barnet, where the conversation is often about volume, massing, and whether your extension will “set a precedent” on the street.

We’ve seen it all: neighbours in Hampstead arguing about sunlight in their garden, committee members in Brent questioning parking ratios, and developers in Finchley scratching their heads over use class changes. At DOR Architects, we take all of this in stride. Because we don’t just design buildings – we navigate the planning maze on your behalf.

Whether you’re a homeowner looking to extend your family home in Golders Green, or a developer eyeing a conversion of a shop unit in Cricklewood into flats, our role is to give your project the best chance of approval.

What is a Planning Application?

A planning application is your formal request to the council to build, alter, or change the use of a property. It isn’t simply a box-ticking exercise – it’s about showing that your scheme fits with planning policies, national guidance, and the character of the surrounding area.

The main types of applications we deal with are:

Householder applications – for single-family homes, extensions, lofts, basements, and garden buildings.
Full applications – for new builds, major alterations, and multiple dwellings.
Change of use applications – such as converting a high street shop (Class E) into residential flats (Class C3).
Listed building consent – required when working with Grade I or Grade II listed properties, where design sensitivity is paramount.

Some projects fall under Permitted Development Rights, meaning no formal planning application is required. But these rights are restricted in many parts of North London – particularly in conservation areas – which makes knowing the difference critical.

Why Planning Applications Matter in North London

North London is an architectural patchwork. Every borough brings its own planning culture.

Hampstead & Highgate – Rich in conservation areas and listed properties. Basements, roof terraces, or modern interventions here need to be handled with diplomacy and finesse.
Barnet & Finchley – Suburban in character, with opportunities for infill housing and generous extensions, but planners keep a close eye on bulk and neighbour amenity.
Cricklewood & Kilburn – Mixed-use, high streets, and regeneration zones. Change of use and residential conversions are common, but density and design quality are under scrutiny.
Westminster & Camden – Heritage-focused, with design quality paramount. Officers want to see schemes that enhance the streetscape rather than disrupt it.

A planning application isn’t just about the paperwork – it’s about understanding the local authority mindset and pre-empting what will raise eyebrows. That’s where our experience pays dividends.

Our Planning Application Service

We provide a full service from the first sketch to the decision notice.

Feasibility & Pre-application Advice
We’ll start with a clear-eyed look at your site. What’s possible? What are the risks? Sometimes a pre-application submission makes sense, giving early feedback from officers before a formal submission.
3D Design & Visualisation
We model every proposal in 3D. This isn’t just about aesthetics – it means planners, neighbours, and committees can immediately understand scale, massing, and impact. It’s a major advantage compared to practices still working in 2D DWG.
Planning Statements & Policy Justifications
We prepare robust written statements to accompany our designs, referencing the London Plan, the NPPF, and borough-specific planning policies. These documents show officers that your scheme isn’t just attractive – it’s policy compliant.
Submission & Liaison
We handle the online submission, liaise with officers during the process, and respond quickly to requests for clarification.
Negotiation & Revisions
Planning often involves dialogue. If an officer raises concerns, we negotiate, refine, and resubmit amendments to keep your application alive and on track.

Planning for Developers

Developers look at planning differently – it’s about return on investment. Our role is to unlock maximum value through smart design and planning strategy.

Use Class Changes – Converting Class E commercial spaces into Class C3 residential can unlock significant uplift. We’ve helped developers in Finchley convert shops above high streets into desirable flats.
Infill & Density – Sites in Barnet and Cricklewood often hold untapped potential. By carefully negotiating height and massing, we’ve secured approvals that increase unit numbers without triggering refusal.
Policy Alignment – Boroughs are under pressure to deliver housing. We position schemes as contributions to local housing targets, which strengthens the case for approval.

Our developer clients rely on us to prepare applications that are persuasive, profitable, and aligned with planning strategy.

Planning for Private Clients

For private homeowners, planning is less about ROI and more about lifestyle. You want more space, more light, or a home that finally fits your family. But the hurdles can be just as tough.

Extensions & Basements – In Hampstead and Golders Green, these are heavily scrutinised. We prepare daylight/sunlight studies, neighbour impact assessments, and design statements to smooth the process.
Loft Conversions & Roof Extensions – Often straightforward in suburban Barnet, but challenging in conservation areas. We know where pushback will come and how to frame your proposal.
Neighbour Objections – We prepare clear visualisations and policy-backed responses to objections, ensuring your voice is heard above the noise.

Our aim is to reduce the stress of planning, so you can focus on the exciting bit – imagining your new home.

Costs of a Planning Application

Planning costs fall into three categories:

Statutory Fees – Paid directly to the council. As of 2025, a householder application is £258, while full applications start from £578. Larger schemes cost more.
Architectural Fees – Our planning services are typically an add-on to Stage 2–3 design work. We provide fixed-fee quotes so you know exactly what to budget.
Consultant Reports – Some applications need specialist input:
- Heritage statements for listed buildings
- Daylight/sunlight reports for extensions
- Transport assessments for multi-unit schemes
- Arboricultural reports where trees are affected

We’ll guide you through which are necessary and bring in trusted consultants when required.

Common Risks & How We Manage Them

Planning isn’t risk-free. Refusals happen. But we reduce risk by planning strategically.

Overlooking & Privacy – We design with sensitive window placements and screening to avoid objections.
Heritage Restrictions – For listed buildings and conservation areas, we balance modern needs with historic character.
Bulk & Massing – We use 3D modelling to demonstrate visual impact, often turning officer concerns into support.
Delays – We stay in touch with case officers to keep applications moving.

By anticipating issues early, we give your application the strongest possible foundation.

Local Authority Insights

We work extensively across North and Central London. Here’s how boroughs differ:

Camden – Strict heritage control, conservation-led. Requires detailed design justification.
Barnet – More flexible with suburban extensions, but careful about scale and precedent.
Brent – Encourages regeneration and density, but sensitive to parking and amenity.
Westminster – Premium design standards, especially for listed and heritage properties.

Knowing the personality of each borough is half the battle.

Case Studies

Hampstead Basement – Secured approval for a basement extension despite initial conservation officer resistance, through sensitive design and daylight studies.
Barnet Infill Housing – Achieved first-time approval for three new-build homes on a backland site, carefully addressing neighbour amenity.
Finchley Conversion – Converted a disused shop into four residential units under Class MA, adding long-term value for the client.
